In this tut we will see how easy add new controls to the table on
example of two new edits with browsers, and how DlgChoice works.

See WM_INITDIALOG and WM_COMMAND processing for COMBO_1 in dialog 
function, and tables of controls and choices in data section.

Simulation of choosing combobox after initialisation is used to
apply choice to controls according to current value of combobox.
Of course, it could be applied directly via DlgChoice, but if there
were complex processing such simulation should be simpler.
